 ### Adding JSON schemas
 
 If you are using external JSON schemas with `$ref`, you can add them to the module before you compile the middleware. Use `handler.addJsonSchema(schema, key)` to compile automatically when used.
 
 `handler.addJsonSchema()` accepts a third (optional) `options` argument. Supported `options` are:
-* `ajv` Custom [Ajv](https://github.com/epoberezkin/ajv) instance. E.g. `handler.addJsonSchema(schema, key, {ajv: myAjvInstance})`. The provided ajv instance can later be passed as an option to the handler to perform JSON validation.

 ### Validation Errors
 
 The library intercepts incoming requests and does validation. It will respond with `400`, `406` or `415` error instances from [http-errors](https://github.com/jshttp/http-errors). Validation errors are attached to `400` instances and noted using `ramlValidation = true` and `requestErrors = []` (an array of errors that were found, compatible with [request-error-handler](https://github.com/mulesoft-labs/node-request-error-handler)).
 
-The errors object format is:
-
-```ts
-interface Error {
-  type: 'json' | 'form' | 'headers' | 'query' | 'xml'
-  message: string
-  keyword: string
-  dataPath: string
-  data: any
-  schema: any
-  meta?: Object
-}
-```
+See [the code](https://github.com/mulesoft-labs/osprey-method-handler/blob/7adb162035e4e593a5bbda8b3e83b1996adc2174/osprey-method-handler.js#L705-L751) for a complete list of errors formats.
 
 **Please note:** XML validation does not have a way to get the `keyword`, `dataPath`, `data` or `schema`. Instead, it has a `meta` object that contains information from `libxmljs` (`domain`, `code`, `level`, `column`, `line`).
